Lunt LS80MT Enhanced Kit - 80mm Hydrogen-Alpha Solar Telescope

LS80MT Enhanced Kit — 80mm Universal Day & Night Modular Telescope Same outstanding pressure-tuned optics. Now with full imaging capability and the complete eyepiece range to match 80mm aperture.

Now with new-generation etalons — every unit individually tested on Lunt's precision metrology equipment. Every specification is verified, not estimated.

The LS80MT Enhanced Kit upgrades two critical areas for observers ready to capture the Sun at 80mm aperture. The B1800 blocking filter provides 18mm of clear aperture that fully illuminates full-frame sensors without vignetting. The complete four-eyepiece flat-field set covers every visual magnification you will use, from full-disk surveys to tight crops on active regions.

The same 80mm f/7 doublet objective. The same Doppler True pressure-tuned etalon at 0.45Å verified bandpass. Now with the optical clearance and eyepiece range to match the resolving power of 80mm aperture.

What You'll See

Everything the LS80MT reveals, now with the magnification range to explore it all. The 8mm eyepiece (70x) pushes in tight on active regions when seeing cooperates, resolving fine magnetic structure and small-scale brightenings. The 12mm (47x) is your workhorse for surface features and prominence detail. The 16mm (35x) provides the sweet spot between magnification and field of view for extended observing sessions. The 19mm (29x) pulls back for full-disk views and limb surveys. All four eyepieces share consistent 60° apparent fields and 0.1% AR coatings, minimising ghost reflections in the narrow-band optical path. Switch between eyepieces and the view stays clean at every magnification.

Why This Package

The B1800 is the blocking filter that serious solar imagers choose for 80mm systems. Its 18mm clear aperture ensures your full-frame sensor sees the complete, unvignetted image circle. Combined with the 2" focuser's ZWO EAF compatibility for motorised focus control, this package is ready for dedicated imaging sessions from day one. For visual observers, four dedicated eyepieces mean you always have the right magnification without compromise. Solar conditions change constantly — seeing fluctuates, active regions evolve, prominences erupt. Having 29x through 70x at your fingertips means you are always observing at the right power for what is happening on the Sun. And like all Lunt 80mm systems, the Enhanced is fully double-stack capable — add the SFPT module at any time to bring combined system bandpass to <0.28Å.
